My invention relates to gas burners and more particularly to the type ofburners employed in making carbon black.

The principal object of my invention is to produce a burner fromwhichthe maximum yield of carbon per unit of natural gas is obtained.

(lther and further objects of the invention will be in part describedand in part specification is proceeded with:

Tn the accompanying drawings:

Figure l is a side View of the burner,-

ig. 2 is a longitudinal sectional View through the burner;

Fig. 3 is a section on the line 3-3 Fig. i;

Fig. 4. is .1 section on the line H Fig. 1;

lg. 5 is a section on the line 55 Fig. i;

Fig. 6 is a section on the line 66 Fig. i;

Fig. 7 is a view similar to Fig. l, but showing the shell or burner indotted lines.

Referring more particularly to the drawings 1 denotes the burnercomprising a shell 2 of brass or like-suitable metal. The inlet end ofthe shell is open and preferably screw threaded externally as at 3 tofacilitate attachment to a gas supply pipe (not shown). The opposite endor tip of the shell or burner is formed with a small opening orperforation a communicating with a large counter bore 5 of concaveshape, the purpose of which will presently be described. An iron wire orstamping 6 is coiled around the burner and has its free end 7 overlyingthe tip of the burner and in line with the opening at therein, for apurpose also to be explained hereinafter.

A small disk shaped screen 8 preferably of copper, is inserted in theshell 2, in position to cover the opening 4:. The shell is thenpartially tilled with refractory material 9, such as pebbles, -taclrs,scraps of metal, ore or the like, and a second screen- 10 similar to thescreen 8 is inserted in the open end of the shell to hold the refractorymaterial in place. This screen 10 is in turn held in place by a metalcollar ll adapted tlpecitication of Letters Patent.

to fit snugly within the screw threaded portron oil the shell.

Tn operation the threaded portion the gas inlet end of the burner isconnected to any suitable source of natural gas'supply. The gas passingthrough the screens 8 and i0 and refractory material. 9 is broken Alterthe burner has been lighted for a short time, the heat from its owntlame heats the burner and likewise the refractory material containedtherein. This has a tendency to pro-heat the gas before it is ready forcombustion. it also. has a tendency to purity. The counter bore at tipof the burner spreads the flame at its source, giving the flame asteadier column.

The flame then strikes the iron wire at its source. This either exerts acatal tic action or a mechanical action, but in either event it producesthe following results. The combustionproce'eds in such a manner as todestroy or radiate away the blue envelop of the flame, allowing only thered or carbon bearing flame to come in contact with the metal plate (notshown) under which it is being burned thus increasing the yield ofcarbon per unit of natural gas. T have found that the iron wire 6 willnot function properly unless the tip oil the burner is counter bored asshown.
